It uses a solid copper core for superior heat dissipation and conductivity across a broad heat range, paired with a platinum center electrode tip that resists wear far longer than a standard nickel tip. The ground electrode is finished in corrosion-resistant nickel to keep installation and removal easy over the plug's service life, and the semi-surface discharge ground configuration is designed to support consistent, reliable spark performance. With 5,000 ohms of resistance, the NGK 7862 helps suppress radio-frequency interference while maintaining strong ignition output. Its 5\/8 inch hex size fits standard spark plug sockets and wrenches sized for that hex. Always check your engine's maintenance manual and use only the spark plug recommended by your engine's original equipment manufacturer -- using the wrong plug can reduce performance and fuel economy or cause engine damage. The NGK 7862 is part of NGK's Standard\/Laser Platinum spark plug lineup, an OE cornerstone that has provided decades of dependable performance for engine builders and service technicians alike.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e NGK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 7862\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNGK Type Designation:\u003c\/strong\u003e PZTR5A-15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround Configuration:\u003c\/strong\u003e Semi-Surface Discharge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround Electrode Core Material:\u003c\/strong\u003e Nickel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Electrode Core Material:\u003c\/strong\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Electrode Tip Material:\u003c\/strong\u003e Platinum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrical Resistance:\u003c\/strong\u003e 5,000 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size:\u003c\/strong\u003e 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 087295178621\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.15 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the NGK 7862 spark plug?\u003c\/strong\u003e The NGK 7862 is a Laser Platinum spark plug with a copper core, a platinum center electrode tip, and a nickel ground electrode, built for reliable ignition performance and long service life.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the electrical resistance of the NGK 7862?\u003c\/strong\u003e The NGK 7862 has an electrical resistance of 5,000 ohms, which helps suppress radio-frequency interference while maintaining consistent spark output.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat hex size wrench does the NGK 7862 need?\u003c\/strong\u003e A 5\/8 inch hex socket or wrench is the correct size for installing or removing the NGK 7862 spark plug.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat ground electrode configuration does the NGK 7862 use?\u003c\/strong\u003e The NGK 7862 uses a semi-surface discharge ground configuration, part of its design for consistent ignition performance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the center electrode tip made of on the NGK 7862?\u003c\/strong\u003e Platinum.
